When designing a recombinant protein production process, a high number of parallel cultivations must be carried out. That task is typically performed using batch cultures in shake flasks or microwell plates, in which fermentation conditions are not monitored. To overcome that limitation, we combined the SensorDish Reader and Shake Flask Reader systems (from PreSens) with an enzymatic glucose delivery system (EnBase technology from BioSilta Oy) for Escherichia coli cultivations. Our objective was to determine whether SensorDish reader cultures would yield reproducible process data that were directly comparable to those at shake flask scale (left).

Especially in the biopharmaceutical industry, a consistent process development from microliter to industrial scale requires consideration of many different perspectives to completely understand a transition process. We created a design of experiments (DoE) to determine optimal parameters at two different cultivation scales. Such batch-type cultivation principles in orbitally shaken systems (mostly shake flasks, but also microwell plates and bench-scale fermentors) are used to obtain acceptable results with as little effort as possible. Unfortunately, they are mostly carried out without considering the important influence of conditions in large-scale production on product quality and process yield.
